You will find Arisakaicon rifles sporterized like yours at almost every gun show. The collector value is completely gone, however with the receiver sight it could be a good shooter or salvaged for parts. The early rifles had chrome bores. Run a patch down the barrrel and take a look at the rifling. I have bought many over the years. Most of them I paid 50 to 75 dollars for. The bolt can be straightened to original or left as is. Richards microfit has very nice stocks for about 70 dollars. It is too bad it was sporterized but it is what is and you can't hurt it anymore by using it. If you plan to shoot it have the headspaced checked and functioning looked at.
